The Bank of England is expected to leave benchmark interest rates unchanged, but investors will look for hints of inflation pressures, which broke above the central bank’s 2% target in May. The decision is due at 1100 GMT. The blue-chip FTSE 100 index gained 0.1%, led by gains in financials and industrial stocks , while the domestically focussed mid-cap index inched 0.1% higher. GSK rose 0.4% after it set out plans to turn its consumer healthcare arm into a separately listed company, in a move that will deliver an 8 billion pound ($11 billion) windfall and other financial benefits for its underperforming drugs business. Among other stocks, British homebuilder Crest Nicholson Holdings climbed 0.3% after it swung to a half-year profit and reinstated its dividend. St. Modwen Properties jumped 0.4% after it backed the latest sweetened buyout offer by private equity firm Blackstone Group at 1.25 billion pounds ($1.75 billion).
